Discussion
This experiment sought to observe pH and its relation to coloration in some
plants. pH is a method of measuring acidity and alkalinity. The pH of a substance is
dependent upon the concentration of hydrogen ions and hydroxide ions. When there ar

These colors are known to attract pollinators for flowers. The pigment also helps
protect the cells from UV rays. Chlorophyll is a pigment used by plants for
photosynthesis. It has a characteristic green color. The presence of these two

The Worm Turns
Summary:
This article describes the perceived effect of parasitic worms, or helminthes, on
humans and their health. Many scientists, including gastroenterologist Joel Weinstock,
believe that the human immune system benefits from these worms

Conclusion
For this experiment data was collected and analyzed using charts and graphs.
The string length trials showed a clear cause-and-effect relationship: As the length of
string got longer, the number of swings in a minute became fewer. This can be e

Affect of Weight and String Length on the Number of Pendulum Swings.
Purpose
This lab seeks to determine if the number of times the pendulum swings is dependent
on the weight attached to it or the length of the string. Merriam Webster defines
